The grinding process is taken over from the machine grinding process, and further polishing is carried out by the human eye and hand senses. In the 1990s, we developed a robot to automate this process and succeeded in mass production.
Today, the production of even higher-grade products has become the mainstream, and we are aiming for a high level of perfection with a craftsman's sense that can flexibly respond to the delicate and individual differences in blades.
Automation by machine is important, but the superior skills of individual craftsmen are the treasure of Hokiyama cutlery.
The Japanese name for this process is Kumorashi or "fogging", which gives the blade its appearance and accentuates the boundaries of the steel.
